摘要
Particulate solid solutions Bi1-xNixVO4-y were synthesized by solid-state reaction at high temperature. The samples were characterized by X-ray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive Spectrometer (EDS), Brunauer-Emmett-Teller (BET) surface area and Ultraviolet-Visible spectroscopy (UV-Vis). The photocatalytic activity of BiVO4 for photocatalytic degradation of organic contaminants ability in visible light region could be improved by doping of Ni2+. The high visible light photocatalytic activity of Bi1-xNixVO4-y solid solution might be due to the generation of a new band gap and expanding the range of visible light response. It was suggested that the Ni2+ doping was beneficial to effective charge separation of Bi1-xNixVO4-y solid solution, thus improved the photocatalytic activity.
